Xydon has created a place that protects this stone archway so that no mortal horse may some near it, they could try of course, but they have to travel through a land that is filled with predators. There's plenty of rocks and boulders along with giant trees that offer cover for a sneaking predator so that it could surprise un unsuspecting horse and get itself a meal. This is also the place where other immortal beings might enter into this world of Xydon's to try and rescue it from it's selfdestruction.
